Here's a command I wrote long ago using a different way to deal with
options:

  *isee*
Usage: isee format file ...
    Display specified inode information for files passed as arguments.
    Items of the form ``%X'' in format will be replaced for these X:
dev inode ino mode nlink uid gid rdev size atime
mtime ctime now filename
    Parenthesized printf-style format specifications can follow a %
    to override the default format for the various items.
    %filename is the name of the current file argument.
    %now is the time (in seconds) when the command started running.
    The other items are from the stat structure.

    Example: isee "%(40s)filename: %mtime %mode" /dev/null
    Show file modification time and mode of /dev/null

inode is just a synonym for ino.

Instead of a kazillion options, the %-stat-field items identify *what* you
want to see and the printf-style formats identify *how* you want them
shown. Someone in the Murray Hill library added strftime formats for date
fields, a fine addition, in my view. Adding readable user and group names
rather than numerical ids would be worth considering. *Maybe* having a
"rwx"-style form for mode. Sorting can be done by piping the output through
sort. Don't get hung up on shortcomings of the command, just consider how a
few familiar concepts and pipes can be combined to provide a large number
of options.
